使用变量来回显设置数据

Question

I can't think of how to do this in my head so I would like someone to lay this out for me. What I am trying to do is allow a user to set a custom greeting for a email using a variable. So for example, in the body of the email, they'll place "$greeting" which will echo out a random greeting they set {'hey', 'hello', 'hi'}.

can someone explain how I would achieve this?

Answer 1

define your possible greetings in an array

$greetings = array('hey', 'hello', 'hi');

echo out a random one

echo $greetings[array_rand($greetings)];

or

shuffle($greetings);
echo $greetings[0];
